Frequently asked questions
- What is a normal Conicity Index?
- Most adults fall between about 1.0 and 1.5. Thresholds differ between studies and populations, so the index is best used to track change over time rather than as a hard cut-off.
- How is the Conicity Index different from waist-to-hip ratio?
- The C-Index uses weight and height instead of a hip measurement, so it describes abdominal shape relative to overall body size without needing a second circumference.
- Why is there a 0.109 constant?
- 0.109 comes from the geometry of the reference cylinder and makes the index unitless so values are comparable across people.
